#100633 - Unipolar vs bipolar sensors Responding to: ???'s previous message |
I came across 2 types of hall effect sensors, unipolar type TLE4905 which turns on when it faces north pole of the magnet if it was facing upwards (and vice versa) and switches off when the north pole is gone or when it faces the south pole.
So in your case you might be trying to turn the hall effect sensor with the south pole. try turning the magnet or the sensor around and it should switch on. The bipolar type TLE4935 is more sensitive than the unipolar type and it turns on when it faces the north pole while it turns off when it faces the south pole. I'm doing research on brushless starter/generator and I used both sensors. Mahmood |
